COIN-CONTROLLED .V ENDING MACHINE Application filed January 19, 1928.SeralvNo. $247,912.`

This invention relates to vending machines, and particularly to animproved coin controlled vending machine, wherein the )arts have beensimplified while retaining a number of safety or projecting applianceswhich prevent the use of most spurious coins without interfering withthe proper operation oi' the machine when a genuine coin is used.

The object ot the invention is to provide a simplified toi-m of coincontrolled vending machine, wherein the parts are so constructed thatthere is little liability of getting out `of order, while at the sametime functioning properly, notwithstanding alnise through the attempteduse of washers or other spurious coins;

Another object of the invention is to profide a coin controlled vendingmachine which is easy to operate, and which will automatically lockitself against operation when the last article has been vended.

il still further object of the invention is to provide in a coincontrolled vending machine, means for permitting the actuation of themachine once after a coin has been inserted, with the parts so arrangedas to prevent a second operation.

ln the accompanying drawings-P- Figure 1 is a longitudinal verticalsectional view through a vending machine, disclosing aii embodiment or'the invention, the operating mechanism being shown in elevation.

Figure 2 is a longitudinal vertical sectional view through the lowerpart ot the vending machine shown iii Figure 1, said view being takenapproximately on line 2-2 ot' Figure 6.

Figure l is a fragmentary sectional view through Figure 2, approximatelyon line 9i- 3.

Figure 4 is a view similar to Figure 2, but showing the parts movedslightly toward an operated position.

Figure 5 is a fragmentaryY sectional view through Figure 2,approximately on line Figure 6 is a horizontal sectional view throughFigure 1, approximately on line y 6 6, the saine being on an enlargedscale.

Figure 'T is a fragmentary sectional View through Figure approximatelyon line i- Roter-ring to the accompanying drawings by numerals, 1indicates a support of any kind, as for instance, a postor wall. A

screw i2, having a large head, is carried by` the wall 1 and is adaptedto tit into the` slot 3 in the back wall 4. Thisback Wall telescopicallytits into the casing 5 and the cas` ing is held thereto by reason of thefor wardly extending portion 6 having a de-V pending flange 7 engaged bythe bolt-8 of the lock 9. At the lower end, the wall 4 is provided witha forwardly extending sec,- tion 10 carrying one or more lugs 11 whichare adapted to be thrust through desirable openings 12 in the bottom `13of casing 5. lVhen` it is desired to move t-lie casing 5 to secureacress to the interior of the casing, lock 9 is unlocked by a suitablekey and casing 5 grasped at the upper part and swung outwardly untilfree of member 6. The casing is then lowered until free of the lug orlugs 11. The `wall 4 is provided Wit-h a forwardly extending flange 14oneach side which slidingly fits into the casing 5 and..

thereby prevents any one forcing an instrument into the casing at thispoint. In

addition, a` curved bracing member 15, is

soldered or otherwise secured to members l and 10 at the lower end.member acts as a chute for guiding articles vended `from the magazine 16to the bottom 13 near the opening 17. The opening 17 is suliicientlylarge to permit part of a hand to be inserted so that the chewing gum or`other articles vended may be readily grasped and removed. y

The casing 5 is provided with a. trans verse bar 18 near the top, andthis bar cal ries one or more retaining and guiding loops 19 throughwhich the magazine or magazines 16 are looselv forced. As indicated u nin Figure 6, the casing 5 is sufficiently large forthree magazines 16and -three duplicate actuating mechanism. but only one has been showncompletely, but as the others are identical, the description of this onewill apply to the others. It is, of course, evident that in a vendingmachine only one mechanism may be used, or a large number, as eachseparate mechanism and associated parts, are identical with the othermechanisms and associated parts. The magazine 16 is preferablyrectangular because the goods are of that shape, and preferably closedexcept at the front as indicated in Figure 6. One or a large number ofarticles Q0 may be placed in tie magazine 16 and then a follower block21 placed on top.

This bracing This follower block may be of any desired matefial, as forinstance, cast iron or brass, whereby ample weight is provided forholding the articles in proper position to be ejected. Preferably thefollower block 21 is provided with a pair of depending legs 22, therebeing one leg on each side whereby the weight is placed on the articles2O near the respective ends. Pivotally mounted on top of the followerblock 2l is a locking plate 23, which plate is rounded at 2st andprovided with an aperture 25 adapted to receive a pin 2G as the lastarticle 2O is ejected. lhis will prevent the pin 2G and associatedparts, including the plunger 27, from moving back to the position shownin Figure 2.

As the plunger is locked in an inner or operated position, customerswill know that the particular magazine associated with this plunger isempty. It tor any reason, a person should drop a coin into the coin slot28, it will merely drop down in front of the wall 29 and land on thebottom 13 where it may be readily recovered by insorting the handthrough opening 17. At the lower end, the magazine 16 is provided with anotch 30 on each side, said notches accommodating the upstandingportions 3l of the wall 32. In this way the magazine is removably placedin position so that whenever the casing 5 is removed, the magazine mayhe quickly removed so as to supply the same with additional articles 20.

lllhen a coin is dropped through une coin slot 28, it will passdownwardly through the opening 33 and also through the opening Sil intothe space or chamber 35. Il the coin is of magnetic material, as forinstance, an ordinary iron washer, the magnet 36 will attract the sameand hold the coin opposite the magnet so that when the plunger 27 ispushed, the coin will drop down in iront of the wall 29 and strike thebottom 13 without causing an ejection oitx one of the articles 20. Itthe coin is not magnetic but has a hole in the center, it will pass themagnet 36 and strike the shoulder 37 et what may be termed a weighingmechanism 38. lf the coin is of the usual weight it will svving thisweighing mechanism to one side and the coin will drop down until itstrikes the wall 39 and pin 40. As indicated in dotted lines in Figure3, when the plunger 27 is actuated, it will merely push the coin ontothe actuating pin l1 as the coin has a. hole therein. If the coin wasnot magnetic, but not as heavy as a genuine coin, it would rest on theshoulder 3?', and when the plunger 27 is actuated, it would drop pas"the end ot the actuating pin Lil and, the "ore, fail to operate themechanism. li the coin was, however ot the right kind, as tor instance,genuine one cent piece, it would pass the magnet 86, strike shoulder 37and swing the weighing mech anism out of the way and move down until itrestedon the pin ll0 and against the wall 39. llillien the genuine coinis in this position and plunger 2T is forced inwardly, the actuatingwall Lil-2 will push the coin against the end of the actuating pin illand innove the pin and associated mechanism IGrwaidly as Indicated inFigure el. ritter the first slight movement, the enlarged end or sectionLll ol pin ell will move the raclr i3 sutliciently to receive the end otpawl lll into the lirst notch. lt the pressure on the plunger 2T wasreleased, the parts would not move bach, hough the plunger 27 would moveback. However, by the time that the end of pawl engaged the lrst notchin rack d3, the coin would be occupying` a space over but at the left ofwall 29, whereby when the wall d2 and associated parts move bach thecoin will be dropped into the coin container or receptacle do. This,oit' course, will not eject any oit the articles 20, but by againpushing the plunger 2'5", the parts will be further actuated, and it theplunger is pushed in tar as possible, the ejector lo will Yforce thlowermost article 2O onto the chute l5 as indicated somewhat in Fig ure4l and this article will slide down 'to a pointnear opening 1T. Alfterthis actuation, the plunger 2T is released, and 'the parts aain movedbach to the position shown in Figure 2 ready for a second actuation. ltthe plunger 27 was actuated a second time without a coin, it wouldmerely move inwardly without causing an artuation of any ot the parts.rlhis is caused by the tact that the wall Llf2 is really a lil-shapedstructure and rigidly secured to the respective walls 39, so that whenmoved lioiwvaidiy without a coin resting on the pin d0, no movement willbc given to Vthe pin all. The pin Ll1 is guided by raison ot' the tactthat it extends through a suitable aperture in an upstanding wall a?carried by the base plate d8, which base plate merges into the wall 32.A web or upstanding flange i9 is formed integral with or rigidly securedto the auxiliary pin or section Ll1, and to this web is rigidly securedor formed integral therewith, the ejector d6. This ejector consistspreferably oi" a flat plate 50 having an upstanding flange 51 on eachside. The pin 26 is rigidly secured to the plate 5G and extends upwardlythrough the ld-shajicd magnet 36 so that when spring 52 acts to forcethe plunger 27 and walls 39 bacl: to

their itormer position as shown in figure 2, themagnet which is securedto these walls will pull pin 2, ejector dit and associated parts bach totheir starting point. The walls Sti and and as iciated parts, may becalled an actuatini nue as the saine are moved by the plu L.; and c; iscboth a 'forward and rearwa d movcnunt ot the Cil llO

other parts. Unel of' the Walls 39 -is provided with a lateral extension53 through Which plunger 27 extends and to which t e plunger is securedby any suitable means, as for instance, a set screw` The plunger alsoslidingly tits into a suitable aperture in the Wall 32 and through thefront stationary wall 54 as Well as through the front of the casing 5.Walls 32 and 54 are connected by a side plate 55, and in fact, the sideplate 55, wall 54, wall 32 and base plate 4S, may be of one solidcasting or may be made separate and rigidly secured together. The baseplate 48 and Wall 32 are slotted for accommodating the rack 43,auxiliary pin 41' and Web 49.

In respect to the action of the rack 47, it will be noted that theauxiliary pin 41 is provided With a singlenotch 56 which is engaged bythe bar 57, which bar has a pair oi supporting arms 58 pivotally mountedat 59 on the Walls 39 of the actuating frame. Ordinarily, the bar 57 isheld out of notch 56 by a cam 57', but after notch 56 has been movedthrough the `insertion of a coin of the proper size, thebar 57 will dropdown into this notch as shown in Figure 4 so as to force the auxiliarypin 41 and associated parts, including ejector 46, to a fully operatedposition before these parts will move back to their starting point.

In case a Washer having an aperture therein, has been pushed onto pin41, said Washer will remain on pin 41 until the pin 41 has been actuatedby a correct coin. As soon as the pin 41 has been pushed inwardly by acorrect coin as far as it will go, the

coin will press the Washer against ring 59 so as to slightly compressthe spring 60. As soon as plunger 27 is released, the spring 60 willfunction to force the Washer off of the pin 4l, whereby it Will dropinto the coin box along with the genuine coin.

In regard to the Weighing mechanism 38, it Will be noted that the sameis made up ot' plates 61 and 62 connected with' a loop portion 63 whichaccommodates the pintle 64 carried by suitable ears depending from theplate 65, which plate is bolted or otherwise rigidly secured to theextension 66 of the stationary Wall 54. A pin 38 is carried by Wall 39and when the parts are in the position shown in Figure 2, a pin isspaced a short distance from'plate 61 so that a genuine coin may strikeshoulder 38 and then move past the lower part of the plate 61 so as torest on pin 40. Vhen piece of paper or light coin is stopped by theshoulder 37, it remains at this place until the plunger 27 is pushed. Asthe plunger moves, pin 3S will strike plate 62 and swing the parts tothe position shown in Figure 4, whereby paper or spurious coins held bythe shoulder 37, may fall down on to the floor i3. As shown in Figure 4,there is an ample space or chamber' whereby any ofthese foreign articlesmay readily drop out of the way so that a clean path will be providedtorthe next true coin.

When the machine is in the position shown in Figure 2 and a proper coinYis linl serted, it will drop down and strike the shoulder 37 and movethe Weighing device to one side and then Will drop down until` itstrikes the pin 40 in front of the end of pin 41. The plunger 27 is thenpushedin` wardly as far as possible. As the plunger moves inwardly, thecoin is slid along the pin 40 and will strike against the `pini41.l FromFigure 2 it will be noted that the pin 40 extends beyond the Wall 29 sothat whew ever the coin is released it will drop the coin inthe coin boxit' the mechanism is beingproperly actuated. As the pin 41 moves, itWill carry the ejector 46, which ejector will strike the lowermostarticle 2O and torce the same out of the magazine onto the chute 15;` Assoon as this has been done, thefplunger 27 will be released and returnedbythey spring 52. As the plunger is returned, itiv will carry with itthe actuating frame rincluding walls 29, and then in turn will move themagnet 36 back and this magnet will strike the pin 26 and move `the pin26 and associated parts back to their starting `point so that the partsareagain in position fora second actuation.
